FRANK FAGERBERG, OF LINDSBORG, KANSAS, ASSIGNR OF ONE-FOURTH TO ERNEST T. N YGREN AND ONE-FOURTH TO ALBERT F. NYGREN, BOTH OF BRIDGEPORT,

KANSAS.

ENGINE-PRIMER.

To all whom t may concern Faonmniue, and a resi- Be it known that I, FRANK a citizen of the United States,

dent of the city of Lindsborg` county oi McPherson, and State o't Kansas` have invented certain new and useful improvements in Engine-Primers7 ot' which the following iS a specification.

My invention relates to engine primers and particularly to such devices used tor facilitating the starting of internal combustion engines.

The object of this improvement is to provide a device of this character which will be simple in its coustrlu'tion and ellieient in operation.

Other objects will appear hereinafter.

The invent-ion consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best ululerstood hy reference to the aecompanyinef drawing forming a part oit this speeitication, and in which,

Figure 1 is a vertical section taken through the primer embodying my invention, Fig. 2 is a horizontal section of the same taken through the central portion, and Fig. 3 is a vertical section taken substantially at 90 degrees trom that indicated in Fig. 1.

The preferred form of construction as illustrated in the drawing comprises a body member 4 iuelosing a chamber 5 and provided with a removable bottom portion G. Said bottom portion 6 is preferably screw threaded to the body ft and provided with a. gasket 7 to 't'urnish a. fluid-tight joint.

rlwo recesses S are formed in the upper wall ot the receptacle 4 and a recess 9 extends inwardly 'trom the top ot said 'wall and is eut; into the recesses S thereby torming a passage trom the top of the chamber 5 through the top wall ot the receptacle 4 to the outside air.l A. valve seat 1() is fitted tightly in the recess 9 and a spring held valve 11 is fitted in the valve seat 10 and normally remains closed by means of its actuating spring 12. The valve seat 10 is fitted in the body portion 4 securely to form a fluid-tight joint by means ot' a close fit between said elements, or the same may be made fluid-tight by means of solder or its equivalent.

Patented Dee. 16, 1913. Serial No. 741,411.

A passage 13 is provided laterally through the receptacle et and extends through the nozzle llt. Said nozzle is provided with screw threads and is adal'ited to be threaded in the manifold of an internat combustion engine, not shown. The passage 153 is enlarged for a portion ot its length and threaded to receive the threaded valve stem 15.' 'lhe valve stem 15 is provided with a suitable valve coaeting with the valve seat 16 formed in the passage 1?). A helical spring 17 is provided around the extended end of the valve stem 15 under compression to frictionatly lock the valve stem 15 in desired positions.

A diagonalty extending perforation 18 is provided in the upper wall ol the receptacle 4 and communicates with a valve formed in the passage 13. A passage 19 extends longitudinally in the side wall of the receptacle 4 and opens into the 'same discharge opening u ith the perforation 18. A lateral perforation 20 is provided in the lower portion of the Wall, in said receptacle and connects the passage 19 with the lower portion of the chamber 5.

In operation. the nozzle 14 is fitted into the manifold of an internal combustion engine and gasolene or other suitable fuel inserted between the valve l1 and its seat 10 by compressing the spring 12 to permit its passage into the chamber 5. .10 is opened to permit. of .communications through the pertorations 18 and Q() and pas sage 19 from the chamber 5 to the cylinders ot' said engine. The liquid 't'uel being heavier than air 'remains in the lower portion ot the chamber 5 and upon moving the pistons ot tlre cylinder oit. said engine a suetion is created in the chamber 5 which draws the liquid iuel through the perforation Q() and passage 19 and air through the perfor-a` tion 18 and through the passage 13 into said engine to facilitate Starting thereof.

lVhle I ha've illustratedy and described the preferred form of construction for carrying my invention into efi'eot, this is capable ot variation and modification without departing from the spirit of the in'.'ention. l. therefore, do not .Wish to be limited to the precise details of construction settorth, hut desire to avail myself ofsueh variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A device of the kinddescribed comprising. a receptacle having a bottom portion removably secured thereto; a nozzle near the top portion of said receptacle and adapted to be connected with the cylinder of an engine; a valve in the wall of Said receptacle in communication with said nozzle, the upper portion of the Wall of said receptacle being provided withl a perforation permitting of communication from the'upper p0rtion of said receptacle with said valve and a passage in the side wall opening into the lower portion of said receptacle permitting of communicationfrom the lower portion of said receptacle to said valve;v and a spring-held valve for admitting air to the upper portion of said receptacle, substantially as described 2. A device of the kind described comprising a receptacle having a bottom portion removably secured thereto; a nozzle near the top portion of said receptacle and adapted to be connected with the *cylinder of an engine; a valve in the wall of said receptacle in communication with said nozzle, the

upper portion of saidl receptacle being provided with a perforation permitting of communication from the upper portion of said receptacle with said valve and a passage in the side wall opening into Ahe lower portion of said receptacle permitting of communication from the lower portion of saidreceptacle to said valve, said upper wall loting also provided with recesses extending upwardly from the interior of said receptacle anda communication joining the upper ends of,

said recesses; and a spring held valve in said communication adapted to admit air through said recesses into said receptacle, substan tially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRANK FAGERBERG.
